To all whom, 'it may concern:

Be it known that I, JAMES M. Sonoma-iw,-

a citizen of the United States, residing at Stockton, in the county of San Joaquin, State of California, have invented certain new and useful Improvements in Odorless Sewer Systems; and I do declare the followall kinds either for city servicev or for private use such as for country residences, thev object of the invention being to produce a system which will be perfectly odorless in all respects and one which will be out sight and in no way interfere with the general appearance of a residence place and one which when used as s city service will not a necessarily interfere with any farming operations that it might be desired to carry on over soil covering the sewer system. .Also to roduce a system in which the liquids wil be disposed of readily and with no danger of overflow. Also to produce a simple, inexpensive and effective system for the purpose.

These objects I accomplish by means of vaults suitably submerged beneath the surface of the ground and having removable lids, the mainsewer pipes discharging into said vaults, division walls in said vaults to maintain a strictly liquid receptacle on one side and the heavy deposits on the other.

A plurality of submerged pipes are spaced v apart around said l vau ts and communicate preferably with the first water carrying sand and gravel strata in the earth. A ipe leads from beneath the desired liquid llevel in said liquid receptacles to the first of said ipipes and on a level with said liquid in said receptacle and all of the said pipes are conp'nected by means of'pi es disposed at the level of said pipe entering said rst named pipe. Also such other and further construction and relative arrangement of parts are employed as will appear by a perusal of the following specification and claims.

In the drawing similar characters of reference indicate corresponding` parts in the view.

The figure in the drawing represents a A vertical section of my complete improved sewer systemf Referring now more particularly to the characters of reference on the drawings 1 designates the surface of the ground. Submerged below such surface is a vault or tank 2 built of brick, cement or other desired material and having a removable lid 8. A wall 4f extends across the tank 2 dividing the same into a large chamber 5 and a smaller chamber 6, there being a plurality of holes `7 in the wall 4 near its upper end and communicating from the chamber 5 to the chamber 6..

8 designatesthe main sewer discharge pipe which is provided withl a trap 9 previous to its entry into the tank. 2. The said pipe 8 runs at an incline into the vault and .to a point below the permitted level of the liquid in said vault.

' I0 are a plurality of pipes or casingssub'- merged beneath the surfaceof'the earth `and having removable lids L0, which pipes eX- tend to the water sand and gravel strata as. shown in the drawing. 'These pipes are all connected by means of pipes Ll1 disposed at the level of the desired level of the fluid in the tank 2, one of said pipes l0 being connected with said tank by means of a pipe 12 inclined into. said tank to a point below the desired level of the liquid in the tank 2 but connecting with the pipe 10 at 'such level.

In practice the pipe 8 discharges the sewage into the tank 2 and the heavy de osits 13 settle to the bottom of lthe cham er 5 and the liquid fills such chamber and Hows through the holes 7 into the chamber 6 and thence through pipe l2 and pipes 1l into the pipes 10 from' whence it drains iuto the water carrying strata 14.

The object of the holes 7 being below the permitted liquid level is so that fioating matterwill not obstruct the samebut will be on the-1.,.

Atop of the liquid leaving a clear communication through such holes. For a similar reason the pipe 12 is inclined into the liquid below its level to keep every mattei.' other than liquid out of the pipes 10, as is neces- 1 sary to the functions of said pipes.

The liquid is carried from thc pipes 10 by means of the ruiming water in the strata 14 and a plurality of such pipes are provided in order to prevent over ow ofthe system, since when the liquid in any one of said matter excavated from the chamber.

Should any of the pipes 10 become clogged'.

from any reason the oep 10 can be removed and such ipes cleanse Y For a city service a plurality of the tanks 2 could be rovided, either connected or otherwise andy so constructed that when one was bein excavated the remaining ones would act independently thereof. The tanks 2 can be of any depth desired and the pipes 10 can communicate either with the first water strata or with deeper ones as maybe desired. f

The feature 'of the device which makes it entirely odorless is thatthe liquid is continuously carried out of the tank and pipes and thus does not rise above its certain predetermined level and thus does not force the odorless gases out of the tank but rather absorbs and carries the same away by ,the means described.

From the foregoing description/.it may be readily seen that I have roduced a sewer system which substantial y fulfils theV objects of the invention herein. l.

While this specification `sets forth in detail the present and preferred construction of my im roved sewer system, still in practice such p eviations from such detailv may be cceeding resorted to as do ma form a. departure frein the spirit of theiu'vention.

Having thusdescribed my invention what I claim as new and useful and desire to secure by Letters Patent is z- 1. An odorless sewer system comprising a tank submerged beneath the soil, a plurality of pipes disposed around said tank and openinginto a natural subterranean water stratum in the soil, means connecting said pipes with said tank at a predetermined level, as set forth. p

2. A-u odorless sewer system comprisin a tank submerged below the ground and having a removable cap, a discharge pipe running obliquely into said tank, a trap -m said discharge pipe, said discharge pipe discharging into said tank"'=below a predetermined liquid level therein, a wall in saidt tank extending upward to suchv predetermined level, a plurality of holes in said vwall below said predetermined level, an outlet pipe extending outward from said tank below the said liquid level to a point in alinement with said level, and a plurality of vertical pipes connectedl with said outlet lpe and with each other all at the same evel, as described.

In testimony whereof I aix my signature l in presence of two witnesses.
